Tell me how you are – and I know how long you will live

10.02.2012
The way people rate their health determines their probability of survival in the following decades.
Researchers from the Institute of Social and Preventive Medicine at the University of Zurich demonstrate that for ratings ranging from “excellent”, “good”, “fair” and “poor” to “very poor”, the risk of mortality increases steadily – independently of such known risk factors as smoking, low education levels or pre-existing diseases.

How would you rate your health? This is a question that often appears on questionnaires. The answer is linked to the respondent’s probability of survival or death. Needless to say, a pessimistic assessment goes hand in hand with an increased risk of illness or death. It can be assumed that on average people who rate their health as poor have an unhealthier lifestyle, are often in a fragile state of health or are already sick. However, earlier studies that only monitored the participants for a few years after the survey reveal that the correlation persists even if these factors are taken into account.
Self-rating more permanent …
Now, researchers from the Institute of Social and Preventive Medicine at the University of Zurich demonstrate that self-rated health is also linked to the probability of survival or death over a long period of more than thirty years. In the study, which was conducted in Switzerland, men who rated their health as “very poor” were 3.3 times more likely to die than men of the same age who rated their health as “excellent”, and the risk of death was 1.9 times higher in women who rated their health as “very poor” than for those who rated it as “excellent”. Here, the risk increased steadily from an optimistic to a pessimistic rating: people in “excellent” health had better chances of survival than those in “good” health, the latter better chances than those in a “fair” state of health, and so on. “The steady increase in risk and the long time of over thirty years between the self-rating and the end of the observation period render it practically impossible for medical history or a dark foreboding to be main causes of the correlation observed,” explains head of the study Matthias Bopp.
... risk factors taken into consideration
Even taking education levels, marital status, tobacco-related strains, medical history, the use of medication, blood pressure and blood glucose into account, the correlation between self-rated health and mortality only weakened marginally. The difference in the risk of death between the best and the worst rating was still 1:2.9 in men and 1:1.5 in women. “Our results indicate that people who rate their state of health as excellent have attributes that improve and sustain their health,” concludes specialist in preventive medicine David Fäh. “These might include a positive attitude, an optimistic outlook and a fundamental level of satisfaction with one’s own life.”
Doctors called for
The results of the study support the broad concept of health advocated by the World Health Organization not as the absence of disease, but rather as complete physical, mental and social wellbeing. “Good doctors should therefore not just look for the presence of risk factors or diseases, but also check which health resources their patients have and boost and consolidate them if need be,” says David Fäh.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
